Each server pair requires 40 minutes to install.1 You must install the database servers serially before you begin to install the administration and call engine servers.

If you install all four of the administration and call engine servers at the same time, the full parallel installation requires 160 minutes (2 database server installations x 40 minutes each plus 2 parallel installations x 40 minutes).

Greater opportunity for entry errors.

You enter information into the installation wizard for two to four servers at a time.

1If you are installing the Cisco TelePresence Exchange System software on a server that requires a firmware update, the installer automatically begins the update, which typically takes about 30 minutes, before performing the server installation. This time is not included in these estimations.

Serial Installation

Software installation for each server requires approximately 40 minutes when you employ a serial installation. To ensure the proper exchange of information among the Cisco TelePresence Exchange System servers during a serial installation, install the servers in the following order:

1. Install the primary database server.

2. Install the secondary database server.

3. Install the administration and call engine servers. The order in which you install these remaining nodes does not matter.

See the following sections for detailed installation instructions for each server:

Note Although you may use the IMM to remotely run the installer, the Cisco TelePresence Exchange System installation DVD must be inserted into the server. Cisco currently does not support full remote installation by mounting the DVD or image file using the IMM.

Using the IMM to Remotely Install the Cisco TelePresence Exchange System Software

After the restart, the server recognizes the DVD and automatically runs the installer.

Note If you are installing the Cisco TelePresence Exchange System software on a server that requires a firmware update, the installer automatically begins the update. During the update, the system will restart approximately four times. The update typically takes about 30 minutes. If you are installing by using the IMM, you will temporarily lose connectivity during the firmware update.
